Karl Rove: atheist?

This has been bouncing around the blogosphere: according to Christopher Hitchens, Karl Rove is an atheist:

Has anyone in the Bush administration confided in you about being an atheist?

HITCHENS: Well, I don’t talk that much to them—maybe people think I do. I know something which is known to few but is not a secret. Karl Rove is not a believer, and he doesn’t shout it from the rooftops, but when asked, he answers quite honestly. I think the way he puts it is, “I’m not fortunate enough to be a person of faith.”

I wonder if this is true? I have to be skeptical, because it fits too perfectly into my worldview.
